A certain neighbouring country of Finland is doing this already, but for other reasons.

Also immigrant vs expat.

At the time of the pandemic it was hard for us Finns, as they said we should be 2 meters away from each other. Too close!

As a Finn I can confirm this.

But if you want to just use the self-service cashier automats, I think the loyalty card is optional. For scanners though it might be required, I’ve never used those. The self-service cashier points are easy enough for me. 😊
